vlan

I am trying to connect a number of VMs using Open vSwitch. The VMs are on two separate physical boxes. Here is what I did:

Created two tap devices on one physical host
sudo ip tuntap add mode tap tap0 and same for tap1
Bring them up
sudo ip link set tap0 up
Add them as ports to Open vSwitch
(br0 was created as a OVS bridge previously) sudo ovs-vsctl add-port br0 tap0 tag=1

Now I booted the VMs (using VirtualBox) and assigned addresses 192.168.122.11 and 192.168.122.12. Now when I try to ping one VM from another, I get the error Connect: network is unreachable. Since both VMs are connected to the switch on the same VLAN, I expect to be able to ping one from another. What is going wrong here?
